Letters Patent No. 92,514, dated July 13, 1869.

IMPROVEMENT IN SAW-BUCK.

The Schedule referred to in these 4Letters Patent and making part of thesame.

` To all whom it'may concern:

This invention relates to a new and useful improvement in saw-bucks orsawhorses; and

It consists in the construction and arrangement of parts, as will belhereinafter morefully described.

In the accompanying plate of drawings- Figure ..1 represents a sectionalelevation of the sawbuck with the filing-clamps attached, as when filingthe saw, the section being through the line x a: of iig. 2.

Figure 2 is' a top view of the same;

Similar letters of reference indicate corresponding parts.

A represents the ordinary saw-buck, with the addition of the serratedplate B, upon one of the sides of the buck,7 as seen inthe drawing.

C represents lever-jaws, pivoted to the brace D, which brace is firmlyattached to thewbuck, filling, or nearly filling the outer angles of oneside.

E represents the pivots, which form the fulcrum of the lever-jaws.

The arrangement of the fulcrum of` the lever-jaw,

allows a freer action and more leverage than when the cross-round ismade the fulcrum.

The two jaws C are pivoted to the inner sides of the buck, and-areconnected together at their lower ends, by the foot-piece or treadle F.

Each of the jaws is provided with a serrated plate,

the same as B, and it will be seen that the teeth are hooking downward,so as to prevent any upward move-V ment of the stick of wood when beingsawed.

Gr and H represent 4the clamps for tiling the saw. In length theycorrespond with the distance between the partsv of the saw-frame, sothat the saw may be placed vin the clamps without being taken from itsframe.

The clamp H is supported by'dowel-pins in the buck, and is triangular in-form.

The clamp His also supported and ,keptin place by dowel-pins, and ispressed against the saw by bearing-on the foot-piece F. p

The saw (in blue color) is seen between the clamps, and is marked I. y

The clamps, being held or attached by loose dowels or steady-pins, arereadily put in place for tiling the saw,'and detached and laid asidewhen not in use.

It will be seen that the top side of the broad clamp G is marked oil",by parallel lines, at the proper angle with the edge ofthe clamp, togive the right bevel or shear to the teeth of the saw, when the file isheld parallel therewith, thus enabling inexperienced hands to hold thefile in the proper position in ling.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- Y lhe saw-bucklA, when provided with the jaw G and clamps G H, all the parts beingconstructed, arranged, and operating substantially as and for thepurposes described. r 4
